In a fascinating development, a team of researchers at MIT’s Laboratory of Organic Electronics and Nanostructures has developed a paper-like speaker frame that may even be capable of drawing in Noise Canceling. Active noise. Here’s what we know so far.
According to Tech Story, a weak diaphragm speaker can connect to a surface to turn it into an active sound source. The new paper-like speakers provide very little sound distortion while consuming much less power than conventional boosters.
The MIT researchers got rid of the traditional reinforcers and instead used a formed piezoelectric material that can move when a voltage is applied to it. To make sound, it moves air above it. During development, many difficulties arose, such as the inability to attach it to the surface. To overcome this problem, designers at MIT “rethought” their plan and created small domes on piezoelectric material that could vibrate individually. Padded layers are placed on both sides and in the middle to make the paper-like speaker durable and safe from scratches.
According to Tech Story, this paper-thin speaker has a lot of potential uses. It can be used in the cockpit to produce an inverse repeatable sound, similar to how Active Noise Cancellation works. It can also be used in theaters and during amusement park rides to create 3D spatial sound. Since its power consumption is very low, it can be used in devices with limited battery capacity. As promised, there’s no guarantee when paper-thin speakers will be developed for mass-scale use, so we can only wait for traditional custom-improved devices to be replaced. with a speaker as thin as new paper.
